Lexus RX 450hL 2018, smart key or proximity remote and the alarm system I'm looking to install is EXCALIBUR ALARM AL-2075-3DB-L.

I am looking to install this with it 2016-2019 Lexus RX450h Plug & Play Remote Start Kit (Push Button Start) so all help will be much appreciated.

Thank you all again in advance.

The Excalibur Alarm AL-2075-3DB-L does not have a plug and play T-harness for your 2018 Lexus RX 450hL. The Compustar DC3 is a remote starter and alarm system and they have a plug and play T-harness ADS-THR-TL7 made specific to your vehicle that additionally requires about 3 hardwire connections to your vehicle's wiring. The DC3 alone does not come with the remotes, t-harness, shock sensor or siren, you will need to buy those separately. The DC3 requires the proper firmware installed in order to work for your Lexus. Some sellers can install the firmware before shipping it out.
